[Amino acid composition of peptidoglycans isolated from cells of Coryneform bacteria by various methods].

A comparative study has revealed the identity of the amino acid composition of the peptide part of peptidoglycans obtained from the intact cells (the first method) and of the amino acid composition of peptidoglycans isolated from cell walls (the second method). This evidences for the possibility of using the first method when determining types of peptidoglycans for diagnosis of the coryneform bacteria genera.

[Characteristics of growth and changes in the ultrafine structure of bacteria in the course of continuous cultivation on media containing ethanol].

A large number of bacterial strains assimilating chemical ethanol has been isolated using an original technique. Active growth of strains belonging to the genera Pseudomonas and, particularly, Acinetobacter was registered on mineral media containing ethanol. A mathematical model was constructed select a strain of Acinetobacter calcoaceticus K-9 during its continuous cultivation on media containing ethanol.
